Both Mount Saint Helens and the San Andreas Fault (source of the Loma Prieta Earthquake) sit on the Pacific Ring of Fire, but there really is little connection between the two. They both sit on the North American Plate, but San Andreas is a transform boundary with the Pacific Plate (meaning the plates move by each other), while Mount Saint Helens sits on a convergent boundary, where the Juan de Fuca plate is subducting beneath the N. American plate. A connection between the events is unlikely.
The Nazca Plate is an oceanic tectonic plate bordering the South American Plate. These plates are subducting along the Peru-Chile Trench and causing most of the Andean geography we see today as the Nazca Plate is being forced beneath the South American plate.

There was an earthquake about 500 years ago that caused a tsunami that hit the coast of Japan, according to my Geology professor at Pierce College in Puyallup, WA. The earthquake was about 9.0 on the richtor scale, and hit in the fall of 1700, as recorded in Japan. Generally, what happens at that subduction zone is the Juan De Fuca, the last reminent of the Ferallon plate, is subducting under the North American plate due to collision, creating the orogenic belt.

Beneath is a preposition. A little trick to determining if a word if a preposition - over the mountain, under the mountain, beside the mountain, around the mountain, through the mountain, around the mountain, above the mountain, beneath the mountain, up the mountain, down the mountain, from the mountain, to the mountain, etc. If you can't do it to the mountain, it probably isn't a preposition.
The Aleutian Islands were formed by the collision of the Pacific and North American tectonic plates. The Pacific Plate is subducting beneath the North American Plate, creating volcanic activity and earthquakes in the region. This process has led to the creation of the Aleutian volcanic island arc.

The Nazca Plate is subducting beneath the South American Plate, causing the uplift of the Andes Mountains. This geologic activity has created a series of aquifers in the region as water seeps through the fractured rock layers of the mountains, filling underground reservoirs known as aquifers.
